Dear Diary,

My boyfriend broke up with me today...said I gamble and smoke too much. It's not my fault! My mom's a fucking alcoholic, so I should be glad I'm not one as well. Well, I'm only 18, so I guess I have 3 years to figure this shit out.

I'm gorgeous and blonde, with an hourglass figure, so getting another guy should be easy, but I only have a few months before I go off to college...is there any point? Still, I'm so horny...

---

I saw my stepbrother Ian reading a book on hypnotism so I asked him if he could hypnotize me so I'd stop smoking and gambling.

I wrote about Ian before when he and his dad moved in a couple years ago, dear diary, and he hasn't changed much...still skinny, with greasy dark hair...same age as me. He's pretty much a younger version of his father like I am my mother...no idea why she married that skid...maybe he's got a big dick? Ugh, still horny...

Anyway, back to the hypnotism...I didn't trust Ian to try it while I was alone with him, so I asked my mom to keep an eye on us as he walked me through staring at a dangling crystal...so boring...

Well, I guess it was boring for Mom, too, as we had to wake her up after we were done. Stupid ditz. Ian said that it seemed like my mind was just too strong for suggestion. However, he's gonna take psychology in university so he suggested negative reinforcement...basically, every time I gamble or smoke, I have to do something I don't want to, and eventually my mind will associate the behavior with the bad stuff and I won't wanna do it anymore. That seemed smart to me, so I agreed.

---

I had just lit my cig in the backyard when Ian caught me. I hadn't had a smoke all day, so I was nic-fitting hard. When he asked me what the worst thing was I could think of, I was so pissed off and, mixed with how horny I've been, I said having to have sex with him.

He seemed surprised and said he wouldn't make me do that, but then suggested that we 'roshambo' -- that's 'rock-paper-scissors', depending on where you're from -- if I won, he wouldn't hold me to it, but if I lost, my gambling with my pussy would get me a big negative reinforcement. I'm pretty good at roshambo, so I agreed.

One, two, three! I threw rock, because nothing beats rock, right? Then I stood there, my mouth open, as I saw that he had thrown paper! Shit, paper beats rock! I was stuck...Ian looked nervous, but a deal's a deal. He followed me to my room and we took our pants off but I kept my top and bra on. His dick was actually above average in length, maybe 6 1/2 inches? I made him put a condom on, even though I'm on the pill...better safe than sorry, right?

I didn't trust him being in charge so I made him lay back as I straddled him. I was surprised that my pussy was wet -- I guess cause it'd been a while since I'd last had sex -- so I got him inside me pretty easily. He managed to hold off for maybe 5 minutes before he groaned and filled up the condom.

After that, I didn't feel like I needed to smoke anymore that day, so it seemed like the negative reinforcement was working.

---

After school today, Ian asked if I wanted to roshambo again. I said hell yeah...he was totally going down. Once again I threw rock and he threw paper...fuck! Well, yeah, fuck...once again I had to ride his condom-covered cock until he blew, though he lasted a little longer that time. I caught his hand trying to reach up to grab my boobs partway through...just negative reinforcement, creep, not touchy-feely.

The nicotine withdrawal hit me later that night and I got through maybe half of a cigarette before he caught me. My punishment was to go to his room that night and take off all of my clothes before we fucked.

I was really antsy for hours before I heard my stepdad snoring, signaling it was time, and I tiptoed to Ian's room. He was already naked and I gulped upon seeing his slim form lying there, ready for me. I pulled off my sleep shirt, showing off my C-cups, and felt my face heat up as I saw him light up at the sight of my bare breasts. I got up onto his bed and swore under my breath because I had forgotten a condom. I turned to head back to my room but he grabbed my arm and brought up his fist, ready to roshambo. He wanted to gamble for the condom!

I shouldn't have, but after losing twice in a row I figured I was due a win. Once again his paper beat my rock...I was stuck, so I pushed my very wet pussy down onto his raw cock. It definitely felt better, skin-on-skin, even if it was with my weedy stepbrother. My eyes were closed and I was concentrating on the sensations down there when I felt his hands on my tits. "Hey!" I hissed, but we were already doing worse fucking without a condom so I allowed it...it actually helped make what we were doing feel a bit better, and when he moaned and spurted inside me I almost felt the stirrings of something possibly related to an orgasm.

After I got back to my bed, I moved my hands down between my legs to investigate his stuff. I'd only ever had sex with a rubber, and those always got thrown out right after, so I found the white stuff very interesting as it slid between my thumb and forefinger. Even though it was my greasy stepbrother's cum, the idea that wriggling sperm was inside me kinda turned me on, and I started to play with my clit, which was actually quite sensitive by that point. About a minute later, I had an orgasm...finally, some release after that dry spell! Normally, masturbation doesn't do it for me without a lot of effort, which is why I liked having a boyfriend. Well, I thought, at least there was a silver lining to this cloud.

---

Stepdad went camping with some of his loser friends, leaving Ian alone with Mom and me all weekend. Mom wore some undersized shorts and a tight t-shirt showing off her D-cups while she made us breakfast, which I thought was odd for my 41-year-old mother, but she seemed happy. She even gave Ian a peck on the cheek when he complimented her outfit. Something about it bothered me but I couldn't put my finger on it.

He caught me lighting up in the garage later in the day, so made me pull down my pants and lean against the wall as he took me from behind. I didn't even think about roshambo'ing for a condom, and within 10 minutes he shot his hot load inside me. He was definitely getting better at sex...I actually started to feel some twinges of pleasure as the head of his cock got deep inside me on some of his harder thrusts. Afterward, I headed to my room to masturbate again.

---

Last night, I managed to pick the lock on my mom's liquor cabinet when Ian caught me. I hadn't even drunk anything, but he wouldn't listen. Given that I seemed to be escalating, Ian said that my punishment had to escalate as well. He took me into the bathroom, grabbed my birth control dial, and told me to flush tomorrow's pill...I couldn't take the next pill until the day after.

No fucking way, I replied, but we roshambo'd again, leaving me confused as to how he kept beating my rock with paper every damn time! As I flushed it down, I could have sworn I saw 2 pills swirling around the bowl before they joined the sewer crocodiles, but I'd only dropped one in there. Optical illusion, I guessed.

We didn't fuck that night, which seemed odd. Instead, I had a strange dream that I woke up hearing my mom moaning loudly, which made no sense, as Ian's dad was away camping, so I blearily opened her door to find Ian between her legs, his slim form pumping away into her tanned, voluptuous bod. What a crazy dream! Obviously my brain was trying to fill the gap in the semi-regular sex I was having with him, and with Mom dressing so skankily that morning, she took my place...or something.

Ian cried out and thrust deep inside her, filling her with his sperm as she came with him. When he pulled out, even in the dim light I could see the big, dripping creampie he left in her. I worried for a second, but then remembered that Mom was on the pill as well. Then I remembered the second pill in the toilet bowl.

Ian turned toward me, his eyes widening in surprise...then I woke up.

---

Ian roshambo'd me right away this morning. His eyes sparkled as his paper once again crushed my rock. How did that even work? Rock should be able to rip right through paper! We fucked on my bed, this time in the missionary position, which I remembered was how dream Ian had been taking my mom last night. It ended the same way, with his creampie dripping out of my puss, though I didn't cum myself. With this being the day that I couldn't take my birth control pill because of yesterday's punishment, I should have roshambo'd him to use a condom but didn't think about it until it was too late.

Once again, it didn't take much more than a minute to diddle myself to completion after he left.

---

Mom caught me taking money out of her purse to buy cigs, since I was out, and she grounded me for a week. Goddamnit, it's spring break! Ian must have heard all this, as he came into the living room afterward and shook his head, his face serious, though I swear he was hiding a grin. I had to suck his cock before he took me from behind, bent over the arm of the couch. After he filled my pussy with his stuff, he forced me to drop another birth control pill down the drain. That was 2 days in a row!

---

Dear Diary,

Today was really strange. I woke up with Ian already inside me. I'd been having another dream where he had actually fucked my mother right next to me on my bed before filling her curvy body up with his load. I guess that dream really turned me on, as his cock was feeling pretty good inside me that morning. He whispered things in my ear as he fucked me...I don't remember what he said, but it was really hot. Turtle? Pennant? Maybes? Or words that rhyme with those...I can't think of any right now, though. Whatever he said, it really set me off, and I actually orgasmed around his cock, which in turn caused him to blow. I just kept cumming as I felt his hot load shooting inside me.

He spent some time sucking on my nipples afterward, which gave me another small orgasm. I think he mentioned maybes again...dunno why a possibility would turn me on so much...maybes sucking on my nipples? Didn't make any sense.

---

I haven't written in a few days...I've been distracted...so horny that I've actually been asking Ian to roshambo, and I keep losing again and again. I've been cumming every time he's fucked me the last few days. When was the last time I took a birth control pill? So many got flushed, I don't remember. The last one in the dial went down the toilet this morning.

---

My period arrived! I cried...guess I get emotional when I'm hormonal. Ian was understanding when I told him, and he reminded me that it's been a full week since I last had a cigarette, so the nicotine is already out of my system. He told me he was proud of me and I felt all warm and funny.

---

It's been another few days. School started back up and I've had trouble concentrating. Every night I keep having that dream where Ian fucks Mom right next to me in my bed. Last night he managed to cum inside her twice, and she orgasmed pretty loud too.

This morning I woke up with Ian fucking me again. He said he checked and found that my period had finally stopped, so knew we could keep going. I was still pretty tired from those weird dreams, but he's just so eager, y'know? And he keeps telling me how much of a good girl I am, so I couldn't say no. We came together.

---

It's been a few days since Ian last made me fuck him. He said I've done so well with no smoking or gambling, and I had to agree, but...no, it's better when he tells me I'm a good girl instead of when he punishes me.

---

I told Ian that I needed to roshambo him...it had been a week of no sex and I was soo horny! After I threw rock, I gasped when I saw that he had thrown scissors! I won! I started crying...he held me and told me that I didn't need to roshambo anymore...I had won and could ask him for anything, but there was only one thing I wanted: his cock inside of me.

I must have cum five times before he finally arched his back and filled me with his hot stuff, making me cum hard one last time. So good...

---

Dear Diary,

I've been reading some of my older entries and I'm confused. How did I ever think that Ian was unattractive? His cock fits me perfectly, like we were meant for each other, and he may be slim, but at least he's not fat! He makes me feel like a princess, but...in the fairy tales, princesses are trapped in towers...I'm not...trapped...

Um...anyway, Mom says she has big news.

---

Mom's pennant! I mean pregnant! That was a weird brain fart...pregnant. Except Ian's dad freaked out and started yelling. He and Ian are gonna be moving out! I'm crying now...how could he abandon his maybe? Uh, baby. WTF?

---

Ian came back without his dad and moved back into his old room! I'm crying again. Why am I so emotional lately? Oh, right in between periods, duh. Periods...I keep thinking I'm forgetting something...something about the toilet? Maybe I should go clean it...Ian says he likes when I clean the house, like a good girl. Maybe I can get him to have some fun with me first? That cock of his makes me cum so hard...

---

Dear Diary,

It's been a few weeks...hard to concen...consen...uh, think. Even writing this is tough. My grades went way down and I wont be able to go to unversity. Mom's gonna keep the maybe...baby...so we're gonna need money. Ian says he can set up a website to pay the bills, and all ill have to do is have sex with him. I was already doing that! Hes so smart...he sez I'm such a good girl...

I think my period's late...I just rememembered what I forgot...I'm such a ditz...without the pills I'm turtle...turtle...fertile.

Another maybe-baby...Ian's gonna be so busy taking care of all of us, his family. He's so great...I luv him...
